摘要(Abstract)：

快速城镇化和人类活动导致城郊流域水体营养盐污染和富营养化问题加重,识别氮、磷污染对流域水质的管控具有重要的意义。本研究选取长三角典型城郊地区宁波樟溪流域,在流域内根据土地利用类型、地形特征等布设样点,于2016年连续4个季度进行水样采集,研究樟溪流域河流水体氮、磷的含量及形态,及氮、磷在该流域的时空分布特征,并对其来源和影响因素进行分析。研究结果表明,流域内氮、磷分布具有较大的空间差异性,其中NH+4-N(n.d.~1.375 mg·L~(-1))、TN-N(0.570~11.363 mg·L~(-1))、DIP(n.d.~0.169 mg·L~(-1))、TP(0.010~1.908 mg·L~(-1))。在子流域空间分布上,人类活动频度越高的区域氮、磷的浓度越高,各采样点水体不同形态氮含量和磷含量具有明显的季节变化规律:春季和秋季的含量要高于夏季和冬季。本研究选取采样点距城镇距离、距源头距离以及土地利用类型所占采样点缓冲区的比例来表征人类活动的影响,结果表明,TN和TP含量与距城镇距离呈显著负相关关系,表明城镇化水平对流域氮、磷污染的重要影响。另外,典型城郊流域河流水体氮、磷污染主要受土地利用类型的影响,其含量与农业和城镇用地呈显著正相关关系(P<0.01),其含量随人类活动频度的增加而升高。
